In July, Alfred and Pauline Carpenter were found dead in shallow graves in Arkansas just days after they vanished. According to prosecutors, they were murdered at a Kansas county fair where they worked as vendors.

Fowler told detectives he was ordered to carry out the murders and dispose of the bodies as an initiation into the so-called carnival mafia, according to Arkansas Online.

Authorities stated the “carnival mafia” doesn’t exist.
